Watch: Lelia Doolan's Walk for Peace

At 91, peace activist and cultural trailblazer Lelia Doolan sets out from Shannon Airport on a walk to Dublin, joined by a group of supporters calling for peace, Irish neutrality, and an end to the airport’s use by US military aircraft. For Doolan, the walk is both a protest and a bit of fun. She says the Irish people want peace, and she is playing her part in showing it.
